Early this month SWPC published their official updated prediction of
Solar Cycle 25 in a new user-interactive graph format. Their updated
prediction is based on the results of NOAA's Solar Cycle 25 Prediction
Panel.
www.swpc.noaa.gov/products/solar-cycle-progression
SWPC f orecasts a solar maximum between 105 and 125 with the
peak occurring between November 2024 and March 2026. There is
broad consensus that Solar Minimum is ongoing this year -- or may
have already occurred -- and that Cycle 25 will have no major change
in the level of solar activity compared to Cycle 24.
For many years SWPC's solar cycle predictions have used the Royal
Observatory of Belgium's International Sunspot Number. SWPC's official
solar cycle prediction now uses the SWPC sunspot number. The
International Sunspot Number is typically about one third lower than the
SWPC sunspot number.
While this is SWPC's official Cycle 25 prediction, its important to note
there is still divergence among various forecasting methods and members
of the space weather forecasting community. Most forecasts and
forecasters agree that the Cycle 25 is likely to be within plus or minus
20 percent of Cycle 24 and is likely to occur between 2024 and 2027.
